REAR PARK ASSIST
The Rear Park Assist is a driver aid that senses for
obstacles behind the vehicle. Refer to the Warnings,
Cautions, and Notes in this section for system limitations
and usage recommendations.
The Rear Park Assist is active when the driver shifts the
transmission into the REVERSE position, and the parking
brake is not applied, and the vehicle speed is less than
10 mph (16 km/h).
The system can be turned on or off through the Electronic
Vehicle Information Center (EVIC) when the vehicle is in
PARK. Refer to “Personal Settings (Customer-
Programmable Features)” under “Electronic Vehicle In-
formation Center (EVIC)” in Section 4.The system uses four sensors located in the rear bumper
to scan for obstacles up to 79 in (200 cm) away from the
rear bumper fascia. The warning display located above
the rear window provides both visible and audible
warnings to indicate the range of the object.

NOTE:The Rear Park Assist will MUTE the radio, if on,
when the system is sounding an audio tone.
WARNING!
•Drivers must be careful when backing up even
when using the Rear Park Assist. Always check
carefully behind your vehicle, look behind you,
and be sure to check for pedestrians, animals,
other vehicles, obstructions, and blind spots be-
fore backing up. You are responsible for safety and
must continue to pay attention to your surround-
ings. Failure to do so can result in serious injury or
death.

WARNING! (Continued)
•Before using the Rear Park Assist, it is strongly
recommended that the ball mount and hitch ball
assembly is disconnected from the vehicle when
the vehicle is not used for towing. Failure to do so
can result in injury or damage to vehicles or
obstacles because the hitch ball will be much
closer to the obstacle than the rear fascia when the
warning display turns the red indicators ON. Also,
the sensors could detect the ball mount and hitch
ball assembly, depending on its size and shape,
giving a false indication that an obstacle is behind
the vehicle.

CAUTION!
•The Rear Park Assist is only a parking aid and it is
unable to recognize every obstacle, including
small obstacles. Parking curbs might be tempo-
rarily detected or not detected at all. Obstacles
located above or below the sensors will not be
detected when they are in close proximity.
•The vehicle must be driven slowly when using the
Rear Park Assist to be able to stop in time when
the obstacle is detected. It is recommended that the
driver look over their shoulder when using the
Rear Park Assist.
NOTE:
•Ensure that the rear bumper is free of dirt and debris
to keep the system operating properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of the system.
If “Service Park Assist System” appears in the EVIC after
making sure the rear bumper is clean please see your
authorized dealer.
OVERHEAD CONSOLE
The overhead console contains courtesy/reading lights,
an optional universal garage door opener (HomeLink),
storage for sunglasses, and an optional power sunroof
switch.

When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replace-
ment or alternate tires and wheels allow the TPMS to
continue to function properly.CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use aftermarket tire sealants
or balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
23. Charging System Light
This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned ON and remain on briefly
as a bulb check. If the light stays on or comes on while
driving, turn off some of the vehicle’s non-essential

Manual Compass Calibration
If the compass appears erratic and the “CAL” message
does not appear in the EVIC display, you must put the
compass into the Calibration Mode manually as follows:
1. Turn the ignition switch ON.
2. Press and hold the COMPASS button for approxi-
mately two seconds.
3. Press the SCROLL button until “Calibrate Compass”
displays in the EVIC.
4. Press and release the FUNCTION SELECT button to
start the calibration. The message “CAL” will display in
the EVIC.
5. Complete one or more 360 degree turns (in an area free
from large metal or metallic objects) until the “CAL”
message turns off. The compass will now function
normally.
Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the
differences, the variance should be set for the zone where
the vehicle is driven, per the zone map. Once properly
set, the compass will automatically compensate for the
differences and provide the most accurate compass head-
ing.
NOTE:Keep magnetic materials away from the top of
the instrument panel, such as iPod’s, Cell Phones, Lap-
tops and Radar Detectors. This is where the compass
module is located, and it can cause interference with the
compass sensor, and it may give false readings.

72°F (22°C) is the recommended setting for maximum
comfort for the average person; however, this may vary.
NOTE:The temperature setting can be adjusted at any
time without affecting automatic operation.
Air conditioning in this system is automatic.
Pressing the air conditioning control button while
in AUTO mode will cause the indicator in the
control button to flash three times and then turn off. This
indicates that the system is in AUTO mode and request-
ing the air conditioning is not necessary.
The system will automatically control recircu-
lation. However, pressing the recirculation con-
trol button will temporarily put the system in
Recirculation mode (10 minutes). This can be
used when outside conditions such as smoke, odors,
dust, or high humidity are present. Activating recircula-
tion will cause the indicator in the control button toilluminate. After 10 minutes, the system will return to
normal AUTO mode function and the indicator will turn
off.
NOTE:
•The surface of the climate control panel and the top
center of the instrument panel should be kept free of
debris due to the location of the climate control
sensors. Mud on the windshield may also cause poor
operation of this system.
•Extended use of recirculation may cause the windows
to fog. If the interior of the windows begin to fog, press
the recirculation button to return to outside air. Some
temp/humidity conditions will cause captured inte-
rior air to condense on windows and hamper visibility.
For this reason, the system will not allow recirculation
to be selected while in Defrost or Defrost/Floor mode.
Attempting to use the recirculation while in these
modes will cause the indicator in the control button to
blink and then turn off.

WARNING!
The BAS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. The
BAS cannot prevent accidents, including those re-
sulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. Only a safe,
attentive, and skillful driver can prevent accidents.
The capabilities of a BAS-equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user’s safety or the safety of
others.
Electronic Stability Program (ESP)
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESP
corrects for oversteering and understeering the vehicle
by applying the brake of the appropriate wheel. Enginepower may also be reduced to assist in counteracting the
condition of oversteer or understeer and help the vehicle
maintain the desired path.
The ESP uses sensors in the vehicle to determine the path
that the driver intends to steer the vehicle and compares
it to the actual path of the vehicle. When the actual path
does not match the intended path, the ESP applies the
brake of the appropriate wheel to assist in counteracting
the condition of oversteer or understeer.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
The ESP/TCS Indicator Light located in the
instrument cluster, starts to flash as soon as the
tires lose traction and the ESP system becomes
active. The ESP/TCS Indicator Light also

update and the TPM Telltale Light will turn off once the
system receives the updated tire pressures. The vehicle
may need to be driven for up to 20 minutes above 15 mph
(25 km/h) in order for the TPMS to receive this informa-
tion.
For example, your vehicle may have a recommended
cold (parked for more than three hours) placard pressure
of 30 psi (207 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 27 psi (186 kPa),
a temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 23 psi (158 kPa). This tire
pressure is sufficiently low enough to turn ON the TPM
Telltale Light. Driving the vehicle may cause the tire
pressure to rise to approximately 27 psi (186 kPa), but the
TPM Telltale Light will still be ON. In this situation, the
TPM Telltale Light will turn OFF only after the tires are
inflated to the vehicle’s recommended cold placard pres-
sure value.CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when us-
ing replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use aftermarket tire
sealants or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors
may result.
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the TPM sensor.
